I/O, Type
Negative power supply (ground).
Serial data true input.
Serial data complement input.
SPI register access enable. This pin has an internal pulldown.
H = SPI register access mode.
L = Pin mode.
AEC loop filter external capacitor (1µF) positive connection (capacitor is optional).
AEC loop filter external capacitor (1µF) negative connection (capacitor is optional).
Equalization bypass. This pin has an internal pulldown.
H = Equalization is bypassed (no equalization occurs).
L = Normal operation.
Mute reference input. Sets the threshold for CD and (with CD tied to MUTE)
determines the maximum cable to be equalized before muting. MUTE
either unconnected or connected to ground for normal CD operation.
Connect this pin to ground or drive it logic low.
Serial data complement output.
Serial data true output.
Auto Sleep. AUTO SLEEP has precedence over MUTE and BYPASS. This pin has
an internal pullup.
H = Device will power down when no input is detected.
L = Normal operation (device will not enter auto power down).
Positive power supply (+2.5V).
Output mute. CD may be tied to this pin to inhibit the output when no input signal is
present. MUTE has precedence over BYPASS. This pin has an internal pulldown.
H = Outputs forced to a muted state.
L = Outputs enabled.
Carrier detect.
H = No input signal detected.
L = Input signal detected.
Positive power supply (+2.5V).
Connect exposed DAP to negative power supply (ground).
